Basic Principles and Functions of Electrical Machines

of electric machines, thereafter, we shall look at the basic features and principles of operation of electric machines. Determination of machine parameters, basic protections, maintenance, and electric machine applications are also discussed. CLASSIFICATION OF ELECTRIC MACHINES There are several methods of classifying electric machines [6]:

Working Principle of Three Phase Induction Motor

Thus from the working principle of three phase induction motor, it may be observed that the rotor speed should not reach the synchronous speed produced by the stator. If the speeds become equal, there would be no such relative speed, so no emf induced in the rotor, and no current would be flowing, and therefore no torque would be generated.

Induction Motor | Working Principle | Types of Induction Motor

One of the most commonly used electrical motors is induction motor.We also call this motor as asynchronous motor because it runs at speed less than its synchronous speed. Synchronous Speed Here we need to define what is synchronous speed. Synchronous speed is the speed of rotation of the magnetic field in a rotary machine, and it depends upon the frequency and number poles of the machine.

PRINCIPLES OF OPERATION OF SYNCHRONOUS MACHINES

PRINCIPLES OF OPERATION OF SYNCHRONOUS MACHINES The synchronous electrical generator (also called alternator) belongs to the family of electric rotating machines. Other members of the family are the direct-current (dc) motor or generator, the induction motor or generator, and a number of derivatives of all these three.

Synchronous motor - construction and working ...

Construction of a synchronous motor is similar to an alternator (AC generator). A same synchronous machine can be used as a synchronous motor or as an alternator. Synchronous motors are available in a wide range, generally rated between 150kW to 15MW with speeds ranging from 150 to 1800 rpm.

Working principle and types of an Induction Motor ...

Induction Motors are the most commonly used motors in many applications. These are also called as Asynchronous Motors, because an induction motor always runs at a speed lower than synchronous speed. Synchronous speed means the speed of the rotating magnetic field in the stator.
